How to Ingore Metadata in JPG File During Folder Compare

02-Jan-2018, 12:20 PM

I write metadata stored in a database to my jpg files a couple of times per year using Photoshop. When I do this it changes the crc and binary comparison values that BC4 detects. To verify file integrity over time I would like to use BC4 to compare the data content only of my jpg files and ignore their metadata when I do a folder compare. I believe the solution is to use a rules-based comparison and define a file-format for a jpg mask that ignores the metadata in each file. Is this the right approach and how should I proceed?

First, double click a specific picture, and make sure the Meta tab/button is disabled. Then from the Folder Compare, go to the Session menu -> Session Settings, Comparison tab. Leave the default timestamp/size/override enabled, and also enable the Rules-based scan. This will perform the Rules-based scan using the defaults (with meta disabled).

Comment

Issue resolved. I had downloaded the file format for EXIF headers which I think was causing the problem. I reinstalled BC4 and the folder compare works as you describe above, though I don't understand why toggling the meta tab in the picture compare view affects the rules based scan in the folder view.

Comment

The Rules-based scan uses the current defaults for the comparison, and that includes the Meta tab's visibility; if it is visible it is part of the comparison results (which you can see in the bottom left status bar of the Picture Compare as you toggle it on or off).

And yes, sorry about that. The Picture Compare recently added the Meta tab, whereas previously you would have needed the EXIF format download to compare (only) that header information. In the Tools menu -> File Formats list, you can move the formats up or down in the priority list. If EXIF is installed, you can move it lower than the default Picture format; this would allow the Picture format to be the default behavior, but still keeps the other associated formats installed.
